A Laptop Battery Owner's Guide

By Rick Broida, PCWorld

Does your laptop battery give out a lot sooner than it used to? Are you lucky to get an hour or two of work done before you need to start searching for an AC outlet? Sounds like it's time to think about replacing the battery.

Get reader for sticker shock: laptop batteries are expensive! Prices vary from one model to another, but it's not uncommon for new power packs to sell for $100 or more. I've seen some as high as $150. When you consider that brand-new laptops now sell for as low as $300, that can be a tough pill to swallow.

Whether you?re already in the market for a replacement battery or just concerned about the inevitable day when you will be, here are three things you should know:

1. Most laptop batteries start to fail in 1-2 years. This varies depending on your usage, of course, but the average laptop battery is good for around 400 recharges (a.k.a. cycles). After that, it starts to lose its capacity to hold a charge.

That?s why the battery that once gave you, say, 3-4 hours? worth of runtime now peters out after just 1-2 hours. And after a few years, you might be lucky to get an even an hour.
